Computed Radiography (CR) is a digital imaging technology where phosphor imaging plates (IP’s) take the place of conventional radiographic film. Once the IP’s are exposed to radiation, the CR scanner uses a focused laser to read the information from the imaging plate and transfer it to software that renders an image on a computer.
